CI / Build and push docker image (push) Failing after 39s
The lobby was hand-rolled CSS and looked plain. Vendor Bootstrap 5.3 (MIT) under web/vendor so builds stay offline, load it in dark mode and bridge the felt/gold palette onto Bootstrap's CSS variables in a new theme.css; style.css now only owns the game table, cards and scoring summary. Rebuild the lobby, waiting room and shared chrome with Bootstrap components: a shared navbar, creation form as cards with schema-driven controls, roster as a list group with seat/team badges, a seats progress bar and a copy-to-clipboard button on the join code. History, leaderboard, connection/error states and the 404 page use cards, tables and buttons too; the play table itself is unchanged. The copy feedback timer is cancelled when the waiting room is rebuilt by another player joining, fixing a disposed-signal panic that froze the page mid-match.
